I did some migrations like this (mbox2maildir with courier). - Maildir performance depends on the _number_ of messages - Mbox performance depends ont the _size_ of the mailbox - Maildir is better for concurrent mailbox access or mail storage on "bad locks handling fs" like nfs. Here are some hints: _The_ mbox to maildir converter: http://perfectmaildir.home-dn.net/ What is maildir format and why: http://www.qmail.org/man/man5/maildir.html Mbox vs maildir: http://www.courier-mta.org/mbox-vs-maildir/ Maildir softquotas: http://www.inter7.com/courierimap/README.maildirquota.html All those preceding items makes me prefers maildir and particularly postfix+maildrop+courier-imap than other free softwares.
